Princess Leia won’t need your help, but Epson and 3M needs your money if you also want some quality rear projection just like the one used to get people’s attention to this digital booth lady:

It’s not quite a holographic projection, but still…
Anyways, Epson is behind the high quality projector, and 3M developed a film that allied to a thin glass that reproduces the optimized projection of the booth lady.
